Summary Introduction

To review:

The groups of organisms currently living on earth that most resemble the earliest life forms.

Introduction:

The first life forms were primitive single cells, with genetic material and only an outer lipid membrane.

Expert Solution & Answer

Explanation of Solution

The first life forms were similar to today’s prokaryotes. They were prokaryotic cells, with macromolecules inside them, having no membrane bound structures. Fossils of such life forms have been found in Australia and South Africa.

Conclusion

The prokaryotes currently living on earth are most similar to the earliest life forms.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
